Evangelist Ray Comfort is accusing atheist users of down-voting "The Atheist Delusion" movie on film-ratings website IMDB, after the documentary had its premiere at Young Earth Creationist Ken Ham's Ark Encounter theme park in Kentucky.
"Within the first 24 hours of its release, 61 atheists have rated it as a one-star movie. This pulls the average down to a 3.5 stars. That means to someone wanting to know, it's really bad," Comfort wrote on Facebook on Sunday, referring the "The Atheist Delusion" and it's 3.1/10 rating on the IMDB website.
"They have done this with most of our productions, but this one is going to be a real target because it disproves atheism with one scientific question," he added.
"They are worried that people will watch it and realize the insane nature of atheism," he continued. "Watch the atheists swarm in like a bunch of nasty bees, to try and pull it down."
The film claims to be able to "destroy atheism with one scientific question," and features interviews with different kinds of atheists, attempting to convince them in the existence of God.
Comfort said the movie is not likely to change the minds of "the average prod and closed-minded atheist."
"But countless others, tempted to believe the ridiculous lie of atheism, are open-minded, and will be convinced by seeing the irrefutable proof for the existence of God," he added.
Ham, who often writes blogs on his Answers in Genesis website warning against the growing secularization in America, said that his life-sized Noah's Ark theme park continues to be very successful, and posted several pictures online of Comfort's visit.
"It was a busy day yesterday with 6,500 people at the Ark Encounter plus the hundreds of guests we had for the premiere of 'Atheist Delusion,'" Ham wrote on Facebook on Sunday.
Despite the negative user reviews on IMDB, other famous conservative Christian artists, such as actor Kirk Cameron, have praised the movie.
"Classic Comfort mixed with high-resolution logic, breath-taking creation, topped off with quality humor and compassionate Gospel interviews," Cameron wrote in a review about "The Atheist Delusion."
Comfort has said that one of his main reasons for making the movie was to warn atheists about what awaits them in the afterlife if they continue in their non-belief.
"I believe with every ounce of my being that Hell is a very real place. I know that is offensive and that it almost always brings scorn with it. It was Penn Jillette who asked how much we would have to hate someone if we believed that Hell was real and didn't warn him," the evangelist said in July in an interview with Hemant Mehta of "The Friendly Atheist" blog.
